Problem
A benzene molecule absorbs a photon that promotes an electron from a π bonding orbital to a π∗ antibonding orbital. Which region of the electromagnetic spectrum most likely supplies this photon?
(a) X–ray radiation that ejects core electrons
(b) Infrared radiation that excites bond vibrations
(c) Ultraviolet/visible radiation that produces electronic transitions
(d) Microwave radiation that primarily couples to rotational motion
